SPEUIF1CATION forming part of Letters Patent No'. 715,161, dated December 2, 1902. Application lilcd April 25, 1902. Serial No.. 104,645. (No model.)

,To all whom ii may concern:

Be it known that I. J oHN NICHOLAS Sono.- MACHER,.a citizen of the United States, and

y a resident of Chicago, in the eonntyof Cook and State of Illinois, have inventeda new and y Improved Bnbbitting Device, of which the following isa full, clear, and exact description. The object of the invention is to provide a new and improved babbittng device designed for babbitting the hubs of loose pulleys, idler-s, and like. articles and arranged .to keep the pulley or other article in proper central position relative to the core or shaft to insure the proper formation of the babbitt x5 bearing and requiring no subsequent boring I or turning of the bearing.

Theinve'ntion consists of n ovel features and parts and combinations of the saine, as willA pointed out in the claims. Y

A' practical embodiment of thev invention isv represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectional side elevation of the improvement as applied. Figf? isa sectional side elevation of the pulley after it is babbitted. Fig. 3 is a sectional plan viewrof the upper collar in position on the shaftor core, and Fig. 4 is aperspective viewof the upper collar.

'Through the' hub A' of thepulley, idler, or

, likdevice A extends the shaft or core B, pref-` f Grkbly held in an upright position during the 35.1 behliitting process, but which may be .placed in a horizontal position, and on the said shaft orcore are removably secured the collars C and 1),.held in position on the core orshaft.` I n and like articles, comprisingv a supporting- I by'set.-s crews E, as plainly indicated in Figs.V 4e 1 and 3. The collars.C- and D are provided with annular concentric ridges C'D', adapted to engage corresponding l seats or recesses .A2

As, formed concentrically in the ends of the" 'hush A', so as to hold the hub and pulley Ain exact concentric position relative to the shaft or'coreB.`4 .Y The lower collar C is Vthe supporting-collar' for the pulley, and the uppercollafr D is the pouring and vvent collar and'is provided with 5o the pouring-channel D, leading tothe upper redud end of the bearing-recess A?, formed in the hub for .receiving theV labiiitt metal be more fully described hereinafter and then l forming the bearing: F, as plainly shown in Fig. 2. The lower rednced end of the bearing-recess A4 is closed bythe supporting-collar C dn ring the babbittidg process. In the collar D is also formed 'errent-opening or channel D3, preferably located diaxnetrically opposite the channel'D2 and likewise in recister with the recess A".

Now when the several parts are in the position shown in Fig. l and the Babbitt metalis poured into the channel D2 then it flows into the recess A4 and fills the saine around the shaft or core B, as the collar C prevent-s escape of the merel from the recess. Air can escape from ihe recess At through the airvent Diso that the Babbitt metal forms a homo; geneous bearing, thereby avoiding undesirable blow-holes. New byhaving the ridges C' and D' engaging seats en the ends of `the huhA' the latter is heldin perfect true position relative to the shaft or core B, so that the babbitt material poured into the recess A* forinsa bearing for the pulley A. Y

`Having thus described my invention', I
